Miriam Haskell Signed Tailored Brooch marbled Stones

Really cool vintage Miriam Haskell brooch in a slightly tailored style with silver tone metal in shapes of flower buds with the centers marbled looking beads and stones that are probably some type of real onyx or marble family, just not sure on that one. It is in an open slightly irregular oval and in very good condition . Signed on the back and clasp in good working order. Very unusual.
